See FUEL PUMP CONTROL CIRCUIT under COMPUTERIZED ENGINE CONTROLS in appropriate SYSTEM & COMPONENT TESTING article.
• On Camry 2.2L 4-cylinder CNG models, check fuel shutoff valve circuit. See DTC P1190: FUEL SHUTOFF VALVE MALFUNCTION test in SELF-DIAGNOSTICS - CAMRY 4-CYLINDER - CNG article.
• On Land Cruiser, check fuel pump control circuit. See DTC P1200: FUEL PUMP RELAY/ECU CIRCUIT test in SELF-DIAGNOSTICS - LAND CRUISER article.
• On 2001 MR2 with sequential manual transaxle, check throttle body and components for Electronic Throttle Control System (ETCS). See THROTTLE BODY under IDLE CONTROL SYSTEMS in SYSTEM & COMPONENT TESTING - 4-CYLINDER article. Models with sequential manual transaxle may be identified by the shift lever pattern which consists of "R", "N", "S" and "+" in place of the conventional type shift lever pattern and no clutch pedal is used.
• On Sequoia and Tundra 4.7L V8, check fuel pump control circuit. See DTC P1200: FUEL PUMP RELAY CIRCUIT test in appropriate SELF-DIAGNOSTICS article.

Engine Stall During A/C Operation

• Check A/C signal. A/C signal may also be referred to as A/C switch signal or compressor circuit. See appropriate MANUAL or AUTOMATIC A/C-HEATER SYSTEMS article in AIR CONDITIONING & HEATING.
• Check Engine Control Module (ECM) electrical connector for loose, damaged or corroded terminals and repair as necessary. For illustration of ECM location, see THEORY & OPERATION article. If electrical connector is okay, check ECM ground circuits. See appropriate article in WIRING DIAGRAMS. Repair as necessary. If ground circuits are okay, replace ECM with a known-good ECM and retest.
